How to use the online alarm clock

You are finishing up for the evening and heading away from the kitchen, so a 9:24 pm alarm can stop the wheelie bins being forgotten before tomorrow’s collection. It leaves enough time to take them to the kerb without turning the job into something remembered at 10:00 pm, when you may already have settled down.

The reminder needs a little preparation if the phone is likely to become inactive while you are elsewhere in the house. The alarm for the bins will not sound if this page is closed or the device falls asleep before 9:24 pm. Keep the page open, prevent automatic sleep until it rings, and leave the volume at a level you can hear from the room where you are finishing your evening.

Once the containers are outside, dismiss the alarm rather than postponing it and leaving the task uncertain. At this point in the evening, dealing with the collection in one brief trip keeps it from occupying the part of the night reserved for sleep. Put on shoes and a coat beforehand if the weather is damp, then return indoors promptly and continue the routine that leads towards bed.

Common questions

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 9:24 pm?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
